A smile works wonders for the body and mind, lowering stress levels, relieving pain, and improving memory. Science has approved some health benefits to the simple act of smiling. So, if you feel plagued with stress and pain or need a little pick-me-up, try out the power of a smile. Though Not all smiles are expressions of happiness, there is a powerful hidden effect from the act.

The Science behind Smiling

Brain-scan studies show that smiling lowers the level of stress hormones in the brain and boosts neurotransmitters that foster happiness and well-being. Smiling exercises several muscles in the body, many of which are used for moving other body parts without actual movement. Smiling constitutes an exercise that can prevent excess muscle tension, injury, and chronic aches and pains in your body. Here is a list of health benefits associated with smiling.

1. Smiling Relieves Stress

It is proven that happy people are less stressed and more relaxed. Studies show that those who make frequent facial expressions tend to be less stressed and more flexible. Smiles make us feel better and reduce stress hormones in our bodies.

2. Smiling Elevates Mood

Your brain releases stress-reducing chemicals like dopamine and serotonin when you smile. Dopamine is a neurotransmitter that creates a feel-good sensation, while serotonin helps regulate moods and behavior. Even newborns smile when they see their parents because of the hormones in their brains, proving smiling is an inborn act, not learned.

3. Smiling Is Contagious

Smiling is a social behavior that tends to spread from person to person. It can also improve the bond between people. Seeing someone smile also makes you smile with them. This is a synchronicity that draws people together. Smiles are contagious, a great way to make people feel good about themselves and improve their overall moods. A simple smile can brighten someone’s day, even at their worst.

4. Smiling Improves Communication

Facial expressions and emotions can convey a lot of information during social situations. A smile tells someone you are friendly and approachable, while more serious facial expressions may intimidate or make others feel uncomfortable.

5. Smiling Reduces Pain

It is a well-known fact that smiling lowers stress levels and relieves pain. Studies have also found that smiles greatly ease pain by blocking nerve signals from reaching the brain. Smiles are very effective in reducing pain, as they inhibit the transmission of pain signals from the brain to the person’s nervous system.

6. Smiling Boosts Memory

People with dementia often fear that their memories will completely fade away. However, those who regularly smile throughout their lifetime tend to have greater memory capabilities than those who do not. Smiling releases chemicals that improve brain function and boost memory formation.

7. Smiling Makes You Attractive

When you smile, your face becomes brighter and more attractive than when you frown or look depressed. Smiling also leads to a more positive perception of the self, which will help you feel better about your appearance.
The truth is, people are attracted to those who appear friendly, calm, and relaxed. Smiling will do wonders for your overall appearance, especially when you are out in public.

8. Smiling May Lower Blood Pressure

Smiling is a great way to combat high blood pressure, as it increases blood flow to the heart and lowers stress levels. Smiling reduces the heart rate and lowers blood pressure. High blood pressure can lead to heart disease and strokes, so a simple smile is a great way to lower your risk.

9. Smiling Helps You Live Longer

Studies have found that people who smile more frequently tend to live healthier lifestyles and live longer. A good sense of humor and a positive attitude are typical traits of happy and healthy individuals.

10. Smiling Boosts the Immune System

When stressed, your body releases chemicals that affect the immune system. There are also chemicals released when you smile. When you smile, your body relaxes, which boosts the immune system. Smiling can improve the functioning of your immune system, which fights off disease and promotes your overall health.

11. You Feel Better When You Smile

No matter how bad of a day, a smile can make it better. Smiling releases endorphins in the brain that will enhance your overall mood and make you feel good.


The power of a smile can change things from bad to good.
